Lithium Metal Polymer Battery: Towards Optimized Cathodes and Crosslinked Polymer Electrolytes
For the purpose of providing basic but essential electrochemical properties of LMPB, we have manufactured four different LiFePO4 cathodes with different densities and thicknesses. Their physical and electrochemical properties are investigated by using the unit cells consisting of LiFePO4/cross-linked polymer electrolyte/Li metal. In particular, with the optimized cathode and crosslinked polymer electrolyte, high capacity retention could be realized at even 5C and room temperature.
